Fluid Mechanics Seminar: Stéphane Popinet

Surface tension is the driving force of a large number of phenomena of great theoretical and practical importance. In this seminar I will attempt to give a general overview of the theoretical and numerical techniques available to accurately model surface tension at the interface between fluids of different properties. This will be followed by a demonstration of a novel algorithm which guarantees balance and momentum-conservation and is naturally applicable to flows driven by Marangoni stresses.

Bigraphy:Stéphane Popinet received PhD under the direction of Stéphane Zaleski at Paris 6 University in 2000 and then worked as a research scientist at the National Institute of Water and Atmospheric research (NIWA), Wellington, New Zealand until 2013, when he joined Institut d'Alembert of Université Pierre et Marie Curie (UPMC), Paris where he now is a CNRS Directeur de Recherche. He is the creator of Gerris and Basilisk software packages and also an associate editor for International Journal of Multiphase Flow.
